### Virtual Method

# Gio File copy_async

#### Declaration [src]

    void
    copy_async (
      GFile* source,
      GFile* destination,
      GFileCopyFlags flags,
      int io_priority,
      GCancellable* cancellable,
      GFileProgressCallback progress_callback,
      gpointer progress_callback_data,
      GAsyncReadyCallback callback,
      gpointer user_data
    )

#### Description [src]

Copies the file `source` to the location specified by `destination` asynchronously. For details of the behaviour, see g_file_copy().

If `progress_callback` is not `NULL`, then that function that will be called just like in g_file_copy(). The callback will run in the default main context of the thread calling `g_file_copy_async()` — the same context as `callback` is run in.

When the operation is finished, `callback` will be called. You can then call `g_file_copy_finish()` to get the result of the operation.
